Java™ Web Start

Java Web Start version 1.7.0 is included in the Java™ Platform, Standard Edition 7 JDK.

Overview

Java Web Start is an application-deployment technology
that gives you the power to launch full-featured applications with
a single click from your Web browser. You can now download and
launch applications, such as a complete spreadsheet program or an
Internet chat client, without going through complicated
installation procedures.

Java Web Start includes the security features of the Java
platform, so the integrity of your data and files is never
compromised. In addition, Java Web Start technology enables you to
use the latest Java SE technology with any browser.

With Java Web Start, you launch applications simply by clicking
on a Web page link. If the application is not present on your
computer, Java Web Start automatically downloads all necessary
files. It then caches the files on your computer so the application
is always ready to be relaunched anytime you want—either from
an icon on your desktop or from the browser link. And no matter
which method you use to launch the application, the most current
version of the application is always presented to you.
